Title
(DE) FILTERELEMENT MIT BESCHICHTUNG ZUR OBERFLÄCHENFILTRATION
(EN) FILTER ELEMENT PROVIDED WITH A COATING FOR SURFACE FILTRATION
(FR) ELEMENT FILTRE A REVETEMENT UTILISE POUR UNE FILTRATION DE SURFACES
Abstract
(DE)
Eigenstabiles, durchströmungsporöses Filterelement (2) mit einer porösen Beschichtung (10) zur Oberflächenfiltration an seiner Zuströmoberfläche, wobei die Beschichtung (10) aufweist: (a) einen ersten Bestandteil aus Partikeln (12) und/oder Fasern (22); (b) einen anorganischen Binderbestandteil (14; 24), welcher die Partikel (12) und/oder Fasern (22) des ersten Bestandteils aneinander bindet; (c) einen Kleber (16; 26), mittels welchem die porösen Beschichtung (10) an das restliche Filterelement gebunden ist; (d) und einen zweiten Bestandteil (18: 28), welcher als Antihaftbestandteil das Anhaften ausgefilterten Materials an der porösen Beschichtung abschwächt und das Abreinigen des Filterelements erleichtert.
(EN)
The invention relates to an intrinsically stable, porous filter element (2) with a porous coating (10) for surface filtration on a penetration surface, said coating (10) comprising: (a) a first component consisting of particles (12) and/or fibres (22); (b) an inorganic binding component (14; 24) binding the particles (12) and/or the fibres (22) of the first component together; (c) an adhesive (16; 26) by which means the porous coating (10) is bound to the remainder of the filter element; (d) and a second component (18: 28) which, as an anti-adhesive component, weakens the adhesion of filtered materials to the porous coating and facilitates the cleaning of the filter element.
(FR)
L'invention concerne un élément filtre (2) poreux, perméable comprenant un revêtement poreux (10) permettant la filtration en surface sur une surface de pénétration, le revêtement (10) comprenant : (a) un premier composant sous forme de particules (12) et/ou de fibres (22) ; (b) un composant de liaison inorganique (14, 24), lequel fixent les particules (12) et/ou les fibres (22) du premier composant ; (c) une colle (16, 26), au moyen de laquelle le revêtement poreux (10) est relié à l'élément filtre restant ; (d) un second composant (18 ; 28), lequel affaiblit l'adhérence du matériau filtré sur le revêtement poreux, et facilite le lavage à contre-courant de l'élément filtre.
